I do like that idea, I think that's something that could happen in the far future when Botan is more capable. She wouldn't be able to take him on but she would be able to escape with the use of her powers. I just figured some other threat would give Botan (as a woman, who I assume might be able to evade death as a grim reaper) something more to fear. I think the idea you proposed is a solid one and I think that confrontation seems easier to have after Kurama has sort of meddled for some time in Goshi's plans.

Yeah, that's how I was thinking. Maybe Goshi is testing his aura's powers by 'lending' them to a peon and that's who is posing in the school as a student? Maybe the 2-3 demons Kurama/Botan run into the following day (Tue after classes) are assistants to the mock demon and are ensuring things are normal after the death of another classmate. Maybe Goshi is testing his skills which is why he sent a lower rank demon to Kurama's school? Goshi is watching and waiting but wants to ensure his skills are honed perfectly for their next showdown? Maybe he sends other peons to test other skills later on?
